Bioengineering with Miyawakis, landslide victories
This study presents various case studies of effective bioengineering-based landslide risk reduction in the Indian Himalayan Region, other parts of India, and globally. Land movements caused by rainfall can occur on slopes. Based on a time-tested Miyawaki afforestation approach, this paper proposes a project proposal to use slopes that are not typically cultivable towards agroecology, as practiced in the region.
A novel method of engineered primary growth is provided that creates Miyawaki pockets, or tiny plots of afforestation-based bioengineering for subsurface water drainage and improved soil stability. It does this by using ecological datasets and plant groups based on mapillaries. Landslide risk assessment estimates are shown, along with a Factor of Safety and evidence that planned afforestation, or bioengineering on slopes, mitigates the risk.
